GreekPIC Posted November 26, 2005 Report Share Posted November 26, 2005 Try this, you can bulid only the two axes.You'll need a program to convert drawings to toolpaths (for 2D ACES is enough and free, I haven't tried it but I've heard good things about it), and a program to read the toolpaths and move the motors accordingly (TurboCNC is great, I've tried it, also Mach2 and others).

GreekPIC Posted November 28, 2005 Report Share Posted November 28, 2005 Thanks. For the Z-axis, how could I make a momentary SPDT switch turn the motor so many steps on the motor without the motor going more than that many steps if the switch is held closed? Also, how many stemp does a normal stepping motor have in one revolution? What could I add to the circuit to automatically turn the z-axis motor so many steps when the computer tells the cnc machine to start?Why don't you just make a 3-axis machine?I would understand it you wanted to cut down on the costs. In this case you could use a DC motor controled by a relay and limit switches.However if you are using 3 steppers anyhow, why don't just add the 3rd axis and be able to do 3d stuff? A circuit to send the stepper a specified amount of steps to one or the other direction at the flip of a switch would be more complicated than making the 3rd axis on the controller.As for the steps/revolution it depends on the motor but 200 is a fairly common number.Nikolas Quote Link to comment Share on other sites More sharing options...
